sing the Red Dot Finder
U
The Red Dot Finder is a zero magnification pointing tool that uses
a coated glass window to superimpose the image of a small red
dot onto the night sky. The Red Dot Finder is equipped with a
variable brightness control, azimuth adjustment control, and
altitude adjustment control (Fig.a). The Red Dot Finder is
powered by a 3-volt lithium battery located underneath at the
front. To use the Finder, simply look through the sight tube and
move your telescope until the red dot merges with the object.
Make sure to keep both eyes open when sighting.
Aligning the Red Dot Finder
Like all finderscopes, the Red Dot Finder must be properly
aligned with the main telescope before use. This is a simple
process using the azimuth and altitude control knobs.
1.
Open the battery cover by pulling it down (you can gently pry at
the 2 small slots) and remove the plastic shipping cover over
the battery (Fig.b).
2.
Turn on the Red Dot Finder by rotating the variable brightness
control clockwise until you hear a "click". Continue rotating the
control knob to increase the brightness level.
Insert a low power eyepiece into the telescope's focuser.
3.
Locate a bright object and position the telescope so that the
object is in the centre of the field of view.
With both eyes open, look through the sight tube at the object.
4.
If the red dot overlaps the object, your Red Dot Finder is
perfectly aligned. If not, turn its azimuth and altitude adjustment
controls until the red dot is merged with the object.

Slowly turn the focus knobs (Fig.c), one way or the other, until the
image in the eyepiece is sharp. The image usually has to be finely
refocused over time, due to small variations caused by
temperature changes, flexures, etc. This often happens with short
focal ratio telescopes, particularly when they haven't yet reached
outside temperature. Refocusing is almost always necessary
when you change an eyepiece or add or remove a Barlow lens.

The magnification produced by a telescope is determined by the focal length of the eyepiece that is used with it.
To determine a magnification for your telescope, divide its focal length by the focal length of the eyepieces you
are going to use. For example, a 10mm focal length eyepiece will give 80X magnification with an 800mm focal
length telescope.
magnification =
When you are looking at astronomical objects, you are looking through a column of air that reaches to the edge of
space and that column seldom stays still. Similarly, when viewing over land you are often looking through heat
waves radiating from the ground, house, buildings, etc. Your telescope may be able to give very high magnification
but what you end up magnifying is all the turbulence between the telescope and the subject. A good rule of thumb
is that the usable magnification of a telescope is about 2X per mm of aperture under good conditions.

In order for the SynScanTM AZ to correctly point to objects in the sky, it must first be aligned to two to three
known positions (stars) in the sky. As the Earth rotates on its axis every 24 hours, astronomical objects
appear to move through the sky following an arc. With the supplied information, the telescope can replicate
a model of the sky and the movements of astronomical objects. Star alignment can be done anytime during
the observing session by choosing Alignment under Setup Mode, in the Main Menu.
There are two ways to align the SynScanTM AZ Brightest Star alignment and 2-Star alignment. If you are
using the SynScanTM AZ for the first time, and you are not familiar with the celestial object in the sky, we
recommend that you begin with the Brightest Alignment. The Brightest Star alignment will prompt and help
you find the brightest star of a specific direction in the sky at your current site. It is convenient for user to
identify the brightest star in the sky. Before performing the alignment method, make sure that your
finderscope is well aligned with the telescope tube. See the next page for tips on how to choose the
alignment stars. Below describes a step-by-step procedure on how to perform the Brightest Star Alignment:
Brightest Star Alignment
In the alignment screen, select Brightest-Star Align using the scroll keys. Press ENTER to confirm. The
1.
hand control will prompt "Select Region:" for you to select one of the eight directional divisions in azimuth
angle from the north, northeast, east, southeast to northwest etc. Each division covers 90-degree span in
azimuth. That means if you select the
northeast sky, the division will cover from
0 degree to 90 degrees in azimuth,
where North equals to 0 or 360 degree in
azimuth angle, East equals to 90 degree
in azimuth angle, South equals to 180
degree in azimuth angle, and West
equals to 270 degree in azimuth angle.
315 ° ~ 45
The table on the right is the range of
the eight directional divisions.
Once the directional division has been selected, the hand control will calculate and generate a list of the
2.
stars located within this region that are brighter than 1.5 in magnitudes. The stars and planets below 10
degrees, higher than 75 degrees in elevation or fainter than 1.4 in magnitudes will be filtered out.
The name and magnitude of the alignment star will be displayed on the first line of the LCD. The
3.
approximate position will be prompted on the second line. For example, if Arcturus is prompt as
alignment star, its magnitude is 0.0 and location is at 88.1 degree east and 24.1 degree above the
horizon. You will see the LCD display as shown in Fig.k.
For the first alignment star, the mount will not slew to the star automati-
4.
cally. Use the directional buttons to manually slew the telescope to point
to the object in the finder and then center it in the eyepiece. You may
change the slewing speed by pressing the RATE button, and then choose
a number between 0 (slowest) - 9 (fastest).
5.
Once the star has been centered in the eyepiece, if it is a planet the hand control will prompt you to reselect a star from the list as the first alignment star. Otherwise the hand control will prompt a list of objects
for you to choose as the second alignment star. Select an object from the list. The hand control will command the mount to slew the telescope to point to the object. Center the object in the eyepiece again. If
both alignment stars are properly aligned, "Alignment Successful" will display on the LCD. Otherwise,
the warning "Alignment Failed" will show and the alignment will have to be done again. You may exit the
alignment procedure by pressing the ESC key anytime during the procedure.
The slewing speed can be adjusted by
pressing on the RATE button. Then choose
a number between 0 (slowest) - 9 (fastest).

Two-Star Alignment
The two star alignment procedure is similar to the Brightest Star alignment, except that the hand control
will not prompt for you to select a directional region for a bright star. Below describes a step-by-step
procedure on how to perform the Two-Star Alignment:
1.
In the alignment screen, select 2-Star Align using the scroll keys. Press ENTER to confirm.

first alignment star. Using the scroll keys, choose a star you are most familiar with and press
ENTER. The telescope will not automatically slew to the first selected alignment star. Use the
directional buttons to manually slew the telescope to point to the object. Now look through the
eyepiece and adjust the telescope so that the object is centered in the field of view of the
eyepiece. Press ENTER to confirm.
3.
SynScanTM AZ will now provide a list of objects for the second alignment star. Choose a star using
the scroll keys and press ENTER. The telescope will start slewing towards the chosen object.
When the slewing stops, adjust the telescope with the directional keys until the star is centered on
the crosshairs in the finder scope. Repeat the centering procedure to center the object in the field
of the eyepiece and press ENTER to confirm.
4.
If both alignment stars are properly aligned, "Alignment Successful" will display on the LCD.
Otherwise, the warning "Alignment Failed" will show and the alignment will have to be done again.
Following is some pointers on how to choose appropriate alignment stars:
Select two stars that are at least 60 degrees apart. The more distance between the two alignment
stars, the better accuracy the alignment will produce. Choosing two stars with the same altitude in
elevation will also create a better result.

Both the star alignment methods provide alignment adequate for any visual observing purpose. For
applications that require extra high precision in a particular part of the sky, the SynScan

performed in up to 85 zones to cover the whole sky. The area(s) where the chosen alignment star(s) is located
should be already mapped out accurately by the SynScanTM AZ. Further accuracy enhancement is not
necessary. The following provides a step-by-step procedure on how to perform PAE:

the name of the reference object will appear in a blinking mode (3 times). If the go-to command is
sent from the planetarium software, instead of the name of the object, the hand control will
display "Last goto object".
Make sure that the reference object is still in the center of the view and press ENTER. If you do
not wish to record the result, press ESC to abort the operation. After pressing ENTER, the

The result for the star alignments and PAE is stored in the hand control even after the power
has been shut off. You will only need to perform the star alignment once as long as these two
criteria are met: 1. The telescope is moved to its home position (Park the telescope) before
turning off the power. 2. The telescope setup, including the mount, has not been moved.
Accessory change is acceptable as long as it is done with great caution. When the hand control
is turned on for the next time, make sure that the time entered during initial setup is based on
the same source as last time. For example, if you enter the time on your watch during this
observing session, the time you enter next time should also be read from your watch.

dditional RS232 Commands
A
Sending a track rate through RS232 to the hand control
1.
Multiply the desired tracking rate (arc seconds /second) by 4. For example: if the
desired track rate is 120 arc seconds/second (proximately 8 times of sidereal rate),
then the TRACKRATE = 480.
2.
Separate TRACKRATE into two bytes, such that (TRACKRATE =
3.
TrackRateHighByte*256 + TrackRateLowByte). For example TRACKRATE = 480,
then TrackRateHighByte = 1, TrackRateLowByte = 224.
To send a tracking rate, send the following 8 bytes:
a. Positive Azm tracking: 80, 3, 16, 6, TrackRateHighByte, TrackRateLowByte, 0, 0
b. Negative Azm tracking: 80, 3, 16, 7, TrackRateHighByte, TrackRateLowByte, 0, 0
c. Positive Alt tracking: 80, 3, 17, 6, TrackRateHighByte, TrackRateLowByte, 0, 0
d. Negative Alt tracking: 80, 3, 17, 7, TrackRateHighByte, TrackRateLowByte, 0, 0
The number 35 is returned from the hand control.
4.
Sending a slow-Goto command through RS232 to the hand control
1.
Convert the angle position to a 24bit number. Example: if the desired position is 220?,
then POSITION_24BIT = (220/360)*224 = 10,252,743
2.
Separate POSITION_24BIT into three bytes such that (POSITION_24BIT =
PosHighByte * 65536 + PosMedByte * 256 + PosLowByte). Example: PosHighByte =
156, PosMedByte = 113, PosLowByte = 199
3.
Send the following 8 bytes:
a. Azm Slow Goto: 80, 4, 16, 23, PosHighByte, PosMedByte, PosLowByte, 0
b. Alt Slow Goto: 80, 4, 17, 23, PosHighByte, PosMedByte, PosLowByte, 0
The number 35 is returned from the hand control.
4.

Reseting the position of Az or Alt
1.
Convert the angle position to a 24bit number, same as Slow-Goto example.\
2.
Send the following 8 bytes:
a. Azm Set Position: 80, 4, 16, 4, PosHighByte, PosMedByte, PosLowByte, 0
b. Alt Set Position: 80, 4, 17, 4, PosHighByte, PosMedByte, PosLowByte, 0
The number 35 is returned from the hand control.

NEVER USE YOUR TELESCOPE TO LOOK DIRECTLY AT THE SUN.
PERMANENT EYE DAMAGE WILL RESULT. USE A PROPER SOLAR FILTER
FIRMLY MOUNTED ON THE FRONT OF THE TELESCOPE FOR VIEWING
THE SUN. WHEN OBSERVING THE SUN, PLACE A DUST CAP OVER YOUR
FINDERSCOPE OR REMOVE IT TO PROTECT YOU FROM ACCIDENTAL
EXPOSURE. NEVER USE AN EYEPIECE-TYPE SOLAR FILTER AND NEVER
USE YOUR TELESCOPE TO PROJECT SUNLIGHT ONTO ANOTHER
SURFACE, THE INTERNAL HEAT BUILD-UP WILL DAMAGE THE
TELESCOPE OPTICAL ELEMENTS.
